Abstract

The invention provides an organic compound fertilizer which, on dry basis, comprises the following components in percentage by weight: 10 to 40 percent of ammonia sludge, 0.1 to 15 percent of active component, and 50 to 80 percent of auxiliary ingredients. The invention also provides a preparation method and application of the organic compound fertilizer. By ammoniating sludge, the invention improves the nutrition content of the fertilizer on the one hand, and simultaneously change the sludge and organic materials into resources from wastes polluting or harming the environment on the other hand, not only solves the waste treatment problem and improves the environment, but also changes the waste into the resources, and opens up a new way for the raw materials required by fertilizer production.

Description

technical field [0001] The invention relates to an organic compound fertilizer, in particular to an organic compound fertilizer using sludge as a raw material, a preparation method and application thereof. Background technique [0002] Water and soil erosion leads to siltation of rivers and lakes, which needs to be cleaned up in time. If it can be fertilized, it can come from the field and return to the field, which is a great supplement to the fertility of the land. A large amount of organic matter deposited in rivers and lakes has caused eutrophication of the water body, resulting in a large amount of aquatic organisms that need to be removed. At the same time, with the improvement of people's living standards, more and more various types of garbage are produced that need to be disposed of. [0003] As for whether there is any harm in the agricultural storage of sludge, and how much harm is there, there are many studies in this area. Lin Lanwen et al. "Municipal Sewage Slu...
